The Essentials of Your Next Upgrade
This essential builder bundle takes your build to the next level of cooling and includes a CORSAIR 4000D Airflow case, RM850 power supply, and the H100i RGB PRO XT liquid cooler for ideal thermal performance with new, next gen components!
Using a CORSAIR RM850 power supply will give sufficient headroom on system power draws especially when using the new CPUs such as the Ryzen 5000 series and new GPUs such as the RTX 3000 and Radeon 6000 cards.
Before we jump into fans and radiator placement, make sure your motherboard is already installed into the case along with the CPU, RAM, and any M.2 drives you may have to make things easier. Please check your manufacturer’s instructions manual for guidance.
We also have a general PC building guide video here for reference.
Additionally, you may want to have your power supply cables already connected to the PSU, route your 8-pin EPS 12V cable to your CPU’s power connector on the top left side of the motherboard and the 24-pin cable to your motherboard’s power connector.
Install the RM850 power supply in the PSU compartment of the PC case and secure it with the right screws.
Be sure to also connect all the front IO port cables of the PC case correctly at the bottom of your motherboard while you have more space in your case to work with. Use your motherboard’s instructions manual if you need clarifications on the header pinouts.
Now let’s talk about the fans and radiator placement in the 4000D Airflow PC case. Our goal is to mount this 240mm radiator on the top panel of the case while exhausting the hot air out upwards.
First, prepare your H100i RGB PRO XT liquid cooler by mounting the ML120 fans that come with it onto the radiator; same side where the tubes are in a push-configuration. Make sure the front side of the fans are visible when mounted.
Ensure that you have the appropriate brackets clipped onto your CPU block; the H100i RGB PRO XT will come with an Intel mounting bracket pre-installed, but you can find brackets for AMD AM4 and sTRX4 in the box.
When you’re ready, install the radiator with the proper screws under the topside of the case with the tubes at the rear side of the case. If you need help, have a partner hold the CPU block/pump during this process.
Once the radiator is installed, secure the CPU block with the pre-applied thermal paste onto the CPU. Make sure the Corsair logo is facing in the proper upright orientation. DO NOT overtighten the screws on the bracket that hold down the CPU block, use your fingers to secure it just enough that it doesn’t wiggle.
Then connect the USB cable from the CPU block into the internal USB 2.0 header on the motherboard (usually near the bottom side of the motherboard). Connect fan cable into the CPU_FAN header. Connect the ML120 fans on the radiator into the fan splitters from the CPU block; do this along the back side of the case.
Lastly, if you have any additional case fans you’d like to install, go ahead and install those where you feel is needed. Typically, three intake fans on the front panel and an exhaust fan at the rear back panel of the case are ideal for thermal performance. And that’s it!
